9490. 'And you shall overlay it with pure gold' means that all those aspects must be founded on good. This is clear from the meaning of 'overlaying' - when the subject is heaven, meant by 'the ark' - as founding on, dealt with below; and from the meaning of 'gold' as good, dealt with in 113, 1551, 1552, 5658, 6914, 6917. The reason why 'overlaying' means founding on is that good emanating from the Lord as the Sun (for the heat from that Sun is the good of love) surrounds heaven not merely as a general whole but also every heavenly community within heaven specifically, and each angel individually too, and thereby protects them from the intrusion of evil from hell. That which surrounds in heaven serves to stabilize it; for heaven rests against it like a house on its foundation and like the surfaces of the body against the lower and upper layers of air bearing down around them. For that which surrounds also bounds, confines, and contains, and in so doing supports and sustains. From all this it is evident that 'overlaying' means founding on, and 'overlaying with gold' founding on good.

9488. 'And a cubit and a half its breadth' means what is complete so far as truth is concerned. This is clear from the meaning of 'one and a half' as what is complete, the reason why this number means what is complete being that 'three' has this meaning (for the half of a number is similar in meaning to the whole number, because a number that results from multiplication keeps the same meaning as a simple number of which it is the product through multiplication, 5291, 5335. Regarding 'three', that it means what is complete, see 2788, 7715, 9198; and that all numbers in the Word mean spiritual realities, 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 5291, 5335, 5708, 6175, 7973); and from the meaning of 'breadth' as truth, dealt with immediately above in 9487.
